KNIFE-HANDLE.

SPECIFICATION forming part of Letters Patent No. 317,539, dated May 12, 1885.

Application filed Jannryfi, 1885. (No model.) Patented in England November 10, 1884, No. 14,804.

Y To all whom it may concern:

' scales of ivory, pearl, tortoise-shell, porcelain,

and similar expensive scales to a foundation of common and inexpensive material to produce a handle which is as effective as a solid handle of pearl or ivory, and which is much cheaper. I attain this object by the means illustrated in the accompanying drawings, in which- Figure 1 represents a handle, part of the scale being removed, constructed in the solid form with a combinationof metallic and wooden or other equivalent material. Fig. 2 is a cross section through thehandle on the line L M, enlarged. Fig. 3represents ahandle with a metallic foundation, only constructed in a skeleton shape. Fig. Ais a cross-section of the same through the line L M, enlarged. Fig. 5 illustrates the rim, frame, or flange of the handle bent into form before the foundationis run or cast on. Fig. 6 is a section of the same through the line L M, enlarged. Fig. 7 represents the -finished handle. Figs. 8, 9, 10, and 11 represent some other sections, enlarged, which may be used in the construction of the rim, frame, or flange illustrated in Flgs. 5 and 6.

Similar letters refer to similar parts throughout the several views.

The handles which form the subject of my present invention consist of a frame or rim, called the flange of the handle, which is constructed out of a strip of sheet metal of the required breadth, and which may be made as thin as is consistentwith the form and strength required. This strip may be stamped, rolled, or otherwise turned over at each edge. It may be made with a groove or recess along each edge, so as to form a cavity or doubleedged flange to receive the scales. Th s rim, frame, or flange may be made of a variety of sections, and may be either flat or canted, fluted or round. In the event of the handle dation.

being required to be rounded on the edges the flange may also be made round, so as to turn over onto the scale and secure it onto the foundation without any extra groove or recess.

In preparing handles of this construction with a large or ornamental head, it may be stamped in two halves and afterward soldered together, leaving the rim to be bent or grooved or recessed for the reception of the scales, as described. A foundation of white metal or other equivalent material is cast onto and within this rim, frame, or flange, (which has been previously prepared by tinning or other process,) such foundation being made either hollow or solid, or partly solid, or in skeleton shape, and serving to form a support for the scales of the handle to rest upon, and also serving to close and secure together the several parts which constitute the handle.

Theessential feature of my present invention consists in the manner in which the frame, rim,

or flange of the handle is secured to the foundation, and to the construction and material used in such foundation, and also in constructing the foundation of the handle partly of metallic substance and partly of wood or other equivalent material in such a manner that the combination forms a solid and durable handle or haft, and at the same time admitting of the employment of a greater variety in the material and design of which the scales of the handle may be constructed.

In Fig. 1, A A is a part of the foundation, made of wood or other equivalent material, and which is made a little less than the frame, rim, or flange. B B B represent the frame, rim, or flange of the handle, which may be stamped, rolled,and bent of the required form. 0 0 represent the scale or scales, which may be made of a great variety of material and design. D D is the metallic portion of the foun- E E is the tang of the blade. K represents the blade.

On reference to Figs. 1 and 2, the latter being a cross-section through the handle on the lineL M enlarged, it will be seen that thescale O rests upon the foundation A,and is secured by the flange part of the rim or frame B. When the rim and the scales, with the wooden foundation, are fitted together, a space is left between the foundation A and the frame or rim B. Into this space the white metal or other equivalent material D is run or cast, forming an adhesive lining, the rim having been previously prepared, so as to secure the adhesion or fusion of the two metals,which unite at the bolster end of the handle, as shown by the dotted line at H H, thereby securing the several parts which form the hand1e,which has by the prd'cess just described become solid. The hole is then drilled through the White metal and the wood foundation to receive the tang E, which is then inserted in the usual way, and may be made long enough to go right through, so as to be riveted at the end of the handle at B farthest from the blade.

In Fig. 3,which represents a handle with a metallicfoundation, only constructed in a skeleton shape, the foundation is run or cast into the frame in asi milar manner to that described in Fig. 1; but in this case a temporary intermediate foundation like a core-box or mold is used, together with temporary scales fitted to and adapted to work in conjunction with the core-box or mold, so that they can be removed after the foundation D D, with the projections G G, have been cast. For this purpose a slit is provided in each of the temporary scales, as shown at F, which admits of the White metal being sawed through, after which the frame B B B, and the foundation D D,With the projections G G, Will all spring open and so release the temporary scales, 'mold,or core-box. Af-

ter the holes for the tang have been provided through the projection G Gand the bolster end of the foundation at E, the permanent scales can beplaced within the frame B B B and 5 resting upon the foundationD D. Thetang of the blade E will then be inserted,as previously described, and the whole firmly secured to.- gether. Fig. 4 is a cross-section of the same through the line L M, enlarged. I

Fig. 5 illustrates the rim, frame, or flange of the handle, bent into form before the foundation is run or cast on. Fig. 6 is a sect-ion of the same through the line L M, enlarged.

Fig. 7 represents the finished handle, in 4 5 which B B B is the rim, 0 is the scale, K the blade, and L the bolster of the blade.

Figs. 8, 9, 10, and 11 represent some other sections, enlarged, which maybe used in the construction of the rim, frame,or'flange illusgrated in Figs. 5 and 6.

Having fully described my invention, what I desire to claim and secure by Letters Patent 1s-- 1. In combination with an exterior frame or rim and a core or foundation, an interposed cast-metal layer which forms part of the foundation and adheres to said frame, substantially as set forth.

2. The frame B, in combination with the White metal cast therein and the shells O, which protect the sides of said white metal, and are held by the overlapping edges of said frame, substantially as set forth.
